    And be compatible with all of them at the same time.

Create a utility function to hash a password coming from the user.

And another utility to verify if a received password matches the hash stored.

And another one to authenticate and return a user.

def test_get_password_hash():
    from docs_src.security.tutorial005_py39 import get_password_hash

    assert get_password_hash("secretalice")


@needs_py39
def test_create_access_token():
    from docs_src.security.tutorial005_py39 import create_access_token

So, if the `dict` contains:

```Python
{
    "username": "johndoe",
    "hashed_password": "some_hash",
}
```

It will be passed to `UserInDB` as:

```Python
UserInDB(username="johndoe", hashed_password="some_hash")
```

## Create your **FastAPI** code

### Create the `FastAPI` app

```Python hl_lines="46"

Here are some possible ideas:

* An "Init Container" in Kubernetes that runs before your app container
* A bash script that runs the previous steps and then starts your application
    * You would still need a way to start/restart *that* bash script, detect errors, etc.

my_second_user: User = User(**second_user_data)
```

!!! info
    `**second_user_data` bedeutet:

    Nimm die Schlüssel-Wert-Paare des `second_user_data` <abbr title="Dictionary – Wörterbuch: In anderen Programmiersprachen auch Hash, Map, Objekt, Assoziatives Array genannt">Dicts</abbr> und übergib sie direkt als Schlüsselwort-Argumente. Äquivalent zu: `User(id=4, name="Mary", joined="2018-11-30")`.
